When my babies were small it was lists of places where it was "safe" to breast-feed your baby that were going the rounds, but yes, of course, it is always useful for mums to know which stores/cafes in their town can provide that necessary relief when it's suddently urgently needed. Vital for the toddler potty-training stage too to know where every single publically accessible loo is in your area! Not too soon to start collecting the data for that one, either!
